Origen

“ And we pray that words may be given us, as it is written in the book of Jeremiah that the Lord said to the prophet: “Behold, I have put My words in thy mouth as fire. See, I have set thee this day over the nations, and over the kingdoms, to root out and to pull down, and to destroy, and to throw down, and to build and to plant.” [1] For we need words now which will root out of every wounded soul the reproaches uttered against the truth by this treatise of Celsus, or which proceed from opinions like his. ”

“ And we need also thoughts which will pull down all edifices based on false opinions, and especially the edifice raised by Celsus in his work which resembles the building of those who said, “Come, let us build us a city, and a tower whose top shall reach to heaven.” [2] Yea, we even require a wisdom which will throw down all high things that rise against the knowledge of God, [3] and especially that height of arrogance which Celsus displays against us. ”
